Stick with your first decision of the LT040 and OS 46 AX. It will be possibly the best combination of plane and engine. A radio with exponential will be really nice for training and also get you though a few other planes. Once you are confident then get a radio capable to fly the planes you have an interest in.

There is a really big fly in coming up in Bealeton Va not too far from you the second weekend of September. If you get the chance try to visit (Saturday is the best day) to see many types of planes.

Good luck!
